The Environment Protection Authority (EPA) has issued licences to SA Water for the safe and secure short-term storage of redundant asbestos-containing cement pipes, at several of its sites across the state.
Late last year, SA Water submitted a licence application to the EPA to store the material at 31 sites, to formalise long-held safe practices.
People living or working near each site were then invited to provide feedback through the EPA's standard review process.
SA Water's Senior Manager of Customer Field Services Colin Bell said during this time, SA Water directly engaged with these residents and businesses, as well as the 30 relevant local councils, and also provided people the opportunity to tour the facilities.
"One of the main concerns highlighted through our engagement process was that people wanted more general information on how asbestos cement pipes should be safely handled and stored," Colin said.
"We have since provided reassurance that our staff who work with this material are specifically trained to ensure their safety and that of the wider community, and existing procedures fully comply with relevant codes of practice and safety regulations.
"To further improve these safe practices and provide consistency across all of our sites, we have worked with a licensed contractor to organise new enclosed and lockable storage containers."
Another one of the concerns raised was the incorrect perception that SA Water is proposing to build asbestos recycling facilities at its sites.
"This likely arose from confusion with the application name - waste or recycling depots (waste for resource recovery or transfer) - and we have since advised residents that we do not, and have no plans to undertake any asbestos processing at these sites," Colin said.
Around 42 per cent of SA Water's water network is made of cement pipes that contain bonded, non-friable asbestos, which are sometimes removed from the ground when SA Water completes repairs or upgrades.
"With our 24/7 operations, repair works can take place at any time of the day or night when licensed waste handling facilities aren't always open, so we need to make sure any removed sections of pipe are safely stored temporarily at one of our sites," Colin said.
"The pipes are double-wrapped immediately after being removed from the water network and then transported to an SA Water site where they're placed in a special locked storage container, before being permanently disposed of at an EPA-licensed waste facility."
The EPA has approved the short-term storage of asbestos cement pipes at 21 of the 31 sites initially included in SA Water's licence application.
Applications were withdrawn for the other 10 sites after SA Water found opportunities to amalgamate some regions' storage to another of its remote sites.
SA Water is also investigating the potential to store the material at seven new additional sites. Licence applications will be submitted to the EPA prior to any changes being implemented, the public will be invited to submit feedback as per standard process, and SA Water is engaging neighbouring properties.
